This invention relates to avalve structure and particularlyl pertains 'to a metering valve. f Y A In the operation of various hydraulic apparatus it is desirable to maintain a constant flow of liquid to a container and tojprovide other means for causing the container :to become automatically evacuated when a predetermined quantity of'liquid has'been placed within the'container. 'This is espesystems in which flush tanks are disposed in predetermined spaced relation to-each other 'alonga sewer, and are caused to successively @1,5 discharge a given quantity'of water sewage inthe sewer will not beflushed out, and will immediately begin the creation of sewer gas 4with vthe result that quite often 125 workmen entering a sewer when itis in-this condition have met with disastrous'results.

It is the principal object of the presentfin vention, therefore, to provide a metering valve through which water may be delivered to a flush tankand by which valve thevolurne and rate ofviiow of the water may be accurately maintained in said valve, embodying a structure whereby it will bev circulating at all times'and'will thus insure that 5 the size of the' orifice through which'the liquid passes will be at all times yclean andy will be of the area at which it has been adjusted. v f f l V The present invention provides the structure of a lhousing connectedwith a water supply pipe Aand by which pipe water or other liquid isdeliveredfto the housing and caused to flowrtherethrough.- Said.- housing being provided with a discharge orificeffor the. liquid, and within which orifice means are embraced to cause the orice at all times to be maintained clean and clear; said means operating mechanically by impulseprovided by the flowing liquid.

Referring more particularly to the 4draw.-

ings, 10 indicates a sewer fitted with flush tanks-11f These tanks are,l provided with discharge openings V12in their lower wall through which openings the' contents of the Hush tank may be discharged into theV sewer. v A Vsuitable valve mechanism 13 is provided vto automatically vopen the discharge opening 12 when a predetermined volume of liquid is within the tank 11. which in this case is water is supplied to the flush tanks through a water supply pipe 14, which connects with metering valves 15, with which thepresent invention is particularly concerned. Y y Y f l Referringmore particularly to Figs. 2 and The liquid' 4 Vof the drawings, it will be seen that the metering valve comprises a housing 16,I hav ing-a center vchamber'l therein,` the mouth of ksaid chamber being internally threaded to receivea closure plate 18. The chamber 17 accommodates a propeller 19 mounted upon d a-valve stern QOL yThis valve stem has an extending portion 21 rotatably positioned vwithin a bearing opening 22 in the plate 18.

The opposite end of the stem extends through a'bearing opening'QB vin the housing 16 and terminates in a conical endmember 24 which extends through an adjustable lcal opening 25"therethrough, and the seat is threaded into opening 26 in theV housing A cross-head 28 extends diametrically across the end of the housing and provides This seat has -a frusto coni` a bearing surface for the end of the conical valve member 24. This cross-head is secured to an adjusting sleeve 29 by suitable standards 30. The adjusting sleeve is p threaded onto a circular boss 31 formed as a partof -the housing16.

Liquid is delivered to the structure by the pipe 14, which as shown in Fig. 5, is threaded into a tangentially disposed passageway `32`Which communicates with thechamber 17 within the valve housing. `=tfwi'll"-thus -be seen that the water delivered to the chamber 17 will impinge against the radial vanes 33 of the rotary propeller.l 9, Tand will.,thus

cause the propeller and "the valve stemi20 .to; simultaneouslyk and continuously rotate as water continues, to flow through thewa'lve rstructure. The inflow-ing water mayithen pass 4throughrducts 3ft to theifrusto: conical vr.20Opening25 of the Valve seat. 25. v"lhewater will flow, around the valve:stemg24efandvout- Wardly, and will be discharged rat-,the-lower y@Jini-gef; the.. opening in` the' valve. seat 25.
